TIME-LOCK.

ESPECIPICATION forming part of Letters Patent No. 335,174, datedFebruary 2, 1886.

Application tiled May 1, 1584. Serial No. 130,010. (No model To all whomit may concern:

Be it known that I, AQUILLA O. BEHEL, a citizen of the United States,residing at Rockford, in the county of WVinnebago and State of Illinois,have invented certain new and useful Improvements in Time-Locks, whichare fully set forth in the following specification, reference being hadto the accompanying drawings, in which- Figure 1 represents an insideelevation of a section of a vault or safe door with lock appliedthereto, embodying my improvements; Fig. 2, a vertical section of thesame, taken on the line 00 m, Fig. 1; Fig. 3, a section of the same,taken on the line y y, Fig. 2, and on an enlarged scale; Fig. 4., anelevation of the timeworks, with a part of the dial broken away, and onthe same scale as Fig. 3; and

Fig. 5 an elevation of the stop-adjustment detached, and on the samescale as Figs. 3 and 4..

My invention relates to time locks for vaults, safes, &c.' The object ofthe main part of my present invention is to disarrange one or more ofthe tumblers of the lock at the point of setting by the action of thetime-works while running; and the improvement consists in the peculiardevices by means of which this result is effected, and also in devicesby means of which the stop mechanism may be adjusted so as to operate ata longer or shorter interval of time, as may be desired.

I will proceed to describe in detail theconstruction and operation ofthe mechanism by means of which I have carried out my inventionpractically in one way, and will then point out definitely in the claimsthe special improvements which I believe to be new and wish to protectby Letters Patent.

In the drawings, A represents the door or wallon which the mechanism isto be mounted, and B a timer or time-works of any ordinary construction,which need not be particularly described here. A wheel, 0, is mounted ona suitable shaft, which is driven by the timeworks, having its peripherypreferably roughened or serrated to insure the action which will bedescribed presently.

' A permutation lock of any ordinary construction is applied to the dooror wall in the usual way. In the drawings I have shown a lock with twoordinary disktumblers, D and D, the former being the inner one. merelyfor illustration, however, as any number of tumblers may be employed.These tumblers are provided with the usual notches, d d, in theirperiphery for the reception of the bolt E, the latter being of any form,construction, and arrangement suitable for the purpose. On the innerface of the tumbler D there is also a pin, d located in this instancenear the periphery of the tumbler and about opposite to the notch (l. Arod or bar, F, is mounted at its respective ends on crank-arms G and G,and these arms are placed on suitable journals, 9 9, so as to be free toswing. In the drawings they are arranged on opposite sides of the bar F,but this is simply to accommodate the timer, and is of no specialimportance. The parts just mentioned are so arranged that the bar F, bythe swinging of the arms,will move back and forth in a plane aboutparallel to the inner face of the tumbler D. A spring, H, is coiledabout the arbor of the lower crank-arm, G, with its free end arranged toact on a pin, h, near the outer end of this arm, the natural action ofthis spring being to throw up this arm, and with it the bar F, so thatwhen left free to operate, the bar will be held by the spring in theposition shown in full lines in Fig. 1 of the drawings. A spring, I, isattached to the bar F by one end, the other being free and bent to forma rather sharp curve, i, projecting out from the edge of the bar overthe tumbler D. This spring, as shown in the drawings, is fastened to ablock, which in turn is secured to the back side of the bar, and so thefree end of the spring may be pressed inward behind the bar. The partsare so arranged that when this spring-bar is in its free position due tothe action of the spring H the projectingbend of the spring I willbeabout opposite to the notch cl in the tumbler D when the latter is inproper adjustment to receive the bolt, and also so that this portion ofthe spring will stand in the path of the pin d as the tumbler isrotated. Obviously then with just the parts mentioned above the tumblerD could never be set, for suppose it to be rotated in the directionindicated by the arrow in Fig. 1 of the drawings, it will be seen thatThis is the pin will come in contact with the spring I before the pointof adjustment is reached, and that in its further movement it will acton the spring to depress the bar F, and that it will not escape fromcontact with the spring until after the point'of adjustment is passed,and at the point of adjustment the spring, and

in fact all the time from the moment the pin strikes the spring until itis about to be .released therefrom, is constantly lifting on the pin bythe action of the retracting-spring H, so that if the tumbler isreleased at any time before its pin leaves the spring on the bar F itwill be immediately thrown back out of adjustment by the lifting actionof the spring I on the tumbler-pin. As soon as the pin escapes from thespring the bar will, of course, at once be thrown up into its normalposition, and the same effect will be produced when the pin of thetumbler is brought around into the same position again.

Now, to secure the objects which I have in view it will be seen at oncethat it is necessary to provide some device for holding the bar out ofposition to act on the tumbler, as described, at such times as it isdesired toleave the lock free to be opened, and also to provide foroperating this device by the timer so as to throw it out of engagementwith the bar when the timer is running and it is desired to prevent theworking of the combination. To effect these results I provide alonglever, J, pivoted near its middle to the free end of a supporting-arm,K, the other end of which is pivoted to the timer-frame or any otherconvenient support. On the bar Fis a stop-pin, f, with which one end ofthe lever J is adapted to engage when the bar F is thrown down to itslowest point by the pin on the tumbler, as described above, andobviously it will hold it in this position until disengaged therefrom,so that under this arrangement the tumbler may be properly adjusted andset for the reception of the bolt. The other end of the lever J extendsto the wheel 0, so as to just engage therewith, and is preferablybeveled-or somewhat pointed to make a dog, j. A spring, j, is coiledaround the arbor of this lever, with its outer end attached to the lowerportion of the lever, so that its tendency will be to throw this end ofthe lever inward and cause it to'engag e with the stoppin on the bar F.This movement will of course vibrate the other or dog end of the leverand cause it to be brought in contact with the wheel 0, this positionbeing shown in Fig. 3 of the drawings. In order to insure with certaintythe engagement of the lever-dog with its actuating-wheel, I have, asdescribed above, mounted this lever on a pivoted support, and,obviously, the lifting-force of the bar will operate to force the leverupward to engage with the wheel. To prevent too forcible action or shockin this direction, a retracting-spring, k, is attached at one end to thesupport K, .and arranged to act in an opposite direction to the liftingforce just described. The other end of the spring is attached to anadjustable screw, k, by means of which the retractile force of thespring may be regulated. Preferably a small roller, f, is put on thestop-pin f, to facilitate the engagement and disengagement of the leverand bar. 7

The timeworks are constructed and arranged so as to revolve the wheel 0in the direction indicated by the arrow in Fig. 8 of the drawings, bywhich its effect is to press outward the dog end of the lever, andobviously the effect of this wheel when in motion will be to vibrate thelever and cause it to disengage at once from the stop-pin on the arm F,thereby releasing the latter, when it willat once be thrown up, asheretofore described, and will be in position to prevent the setting ofthe tumbler D, as already explained. When it is desired to throw thismechanism out of action, the time-movement not being in opcration, asalready explained, the bar is thrown down, the lever will engage withthe stop-pin .thereon, and these parts will stand in the position shownin dotted lines in Fig. 1 of the drawings, and the tumbler D may thenbeproperly adjusted and set before the pin will come in contact with thespring on the arm. When, however, it is desired to bring this mechanisminto action, so as to prevent'the setting of the tumblers, the timer isof course put in operation and set, the spring-bar is released from thelever and is thrown up, taking the position shown in full lines in, Fig.1 of the drawings.

As already explained, if the tumbler D is turned around, it cannot beleft at the settingpoint, for then the bar will operate to at once turnit out of adjustment, and if it is turned still farther around willthrow the bar down until the pin escapes from the spring and thedog-lever engages with the stop-pin on the bar, as shown in dotted linesin Fig. 1 of the drawings. This position will be only momentary, for thedog end of the lever is at once brought into contact with theactuating-wheel 0, when, as already explained, the lever is at oncedisengaged i'rorn the bar and the latter rises again to assume itsstopping position, and this action will be repeated over and over againas often as the tumbleristurned and so long as the timer is running; butwhen the timer stops the tumbler is turned around until the bar isthrown down to permit the dog-lever to engage therewith, when of coursethe latter retains its position and holds the bar permanently out ofaction, and-the tumbler may then be set. In order to retain the bar Fwithin a limited move ment, one end is bent inward slightly, as shown inFig. 2 of the drawings, and is ar-' ranged between two stop-pins, L andL, placed such distance apart as may be desired for the throw of thebar, and these pins are on a plate, Z, which is fastened to any suitablesupport by slot and screw, so as to be adjustable, thereby providing forthe accurate adjustment of the IIC' throw of the bar to bring thestop-spring into just the position required. It is desirable also toprovide for the lateral adjustment of this bar F, as it mustbe arrangedwith reference to the pin on the tumbler with great nicety. I providefor this by attaching the journals 9 g of the crank-arms to disks 9which are fastened to the wall by means of screws or pins g 0ne on eachside of the journals-and on one side is a slot, 9, through which thefastening screw or pin passes, so that by loosening this screw the diskmay be turned slightly about the other as a pivot, thereby setting thejournals in or out a little, as may be required to bring the bar intothe exact position demanded.

The timer is provided with a setting mechanism similar to that of anordinary alarm-- clock, and I need not stop here to enter into a fulldescription of it, but merely refer to certain of the parts which arenecessary to an understanding of some additional improvements which Ihave made. In this mechanism M is the dial, which is annular, and m thestopdisk, which is carried around once in twent-y- 1 four hours and ,isprovided with a notch, m. A stop-lever, N, is arranged as usual insideof the dial, and is provided with a stop-pin, n, projecting out, so asto ride on the periphery of thedisk m, and actuatedby a spring, n,whichoperates to hold the lever down upon the disk. The free end of the leveris bent inward to form an arm, n", which is arranged to drop directlyinto the gear-wheel c on the shaft of the wheel 0, thereby stopping theworks whenever the lever drops by reason of the pin dropping into thenotch in the disk. The disk in is a twenty-four-hour disk; but sometimesit is of course desirable to havethe timer run more than twenty-fourhours-for instance, over Sunday. To accomplish this I provide astop'slide, 0, supported on suitable guide pins or ways of anydescription, horizontally back of the disk and just below the stop-pinon the lever N. This slide is cut away at one end on its upper edge, asshown in Fig. 5 of the drawings, so that the remaining portion 0 isconsiderably higher than the level cut-away portion 0, and in the loweredge of the slide is a notch, 0 This slide is loose on its supportswithin the limits of the slots 0*, made in it, and is arranged so thatwhen slipped back to its farthest limit the higher surface 0 will beentirely back of the stoppin, and so will present no obstacle to thedropping of the latter into its notch in the disk; but when slippedforward to its full extent this higher portion 0 will be broughtunderneaththepin,therebyholdingitinabout the same position that itoccupies on the general periphery of the disk, and preventing it fromdropping into the notch in the latter until removed.

In order to remove the slide out of the way of the stop-pin, a smallpin, m", is arranged on the inside of the disk in a position to enandthe disk will make another full revolution, which will require fullytwenty-four hours, and during this revolution the pin on its inside willbe brought into connection with the notch on the slide, removing it outof the way, so that when the notch in the disk is again brought underthe stop-pin the latter will fall and stop the works.

In this connection I have also devised an additional device forpreventing the adjustment of the tumblers, which is arranged to act incombination with the mechanism already described, but not in mechanicalconnection therewith, so that if for any reason the timeworks shouldstop before the moment at which it is set, or for any other reason thestop-bar should be carried down and held in this position out of the wayof the tumbler, this additional device will be in position to operateand effectually prevent the setting of the latter. This device consistsof a spring, 1?, mounted on a suitable journahp, and projecting out in anearly horizontal position, so that its free end will extend slightlyover the edge of thetumbler D and be in the path of the pin thereon,asshown in Fig. 3 ofthe drawings. This device is preferably made in twopartsone a straight flat spring, 19, fastened at one end to a rigid arm,10*, which acts as a holder and is mounted loosely on the pivot-pin. Arod, Q, is connected at one end to the spring or its holder,while theother end is connected to the stop-lever of the time-works, so that whenthe latter is raised by the stop-disk the spring will bein the positionshown in Fig. 3, and stand in the way of the pin on the tumbler, butwhen the lever drops into its stopping position by reason of its pindropping into the notch in the disk, this spring will obviously bedropped also and will assume the position shown in Fig. 1 of thedrawings, in which it is out of the way of the pin at the point ofadjustment and will not interfere with the setting of the tumbler. Thearrangement of this spring is such that when in this raised position(shown in Fig. 3 of the drawings) the pin on the tumbler will strike itsome time before the setting-point is reached, and will not be releasedtherefrom until after this point is passed by the tumbler. Obviously,the spring will act, therefore, in a similar way to the spring on thebar F, to prevent the setting of the tumbler, and as it is not connectedto the bar F, if by any accident the timer should stop before the notchin the disk is brought under the pin of the stoplever, therebypermitting the bar Ftobe carnation;

ried down and held in position by its lever, this'spring P willstillremain in operative position and prevent the setting of thetumblers." At the same time when the timer is stopped in the regular waythe spring is thrown down out of the way and will therefore notinterfere with the proper adjustment of the tumblers when the bar F isdepressed and fastened in this position for this purpose.

In order to provide for opening the vault or safe in case an accidentsuch as suggested above occurs, a secondary private combination may bemade known only to some one person, which maybe operated,notwithstandingthe spring P. This may be accomplished by making a second notch,d in thetumbler D, alittle back of the notch 01 of the main combi- This 'notch dshould be so arranged that it will not be brought into setting positionin front of the bolt until just after the pin on the tumbler is releasedfrom the spring P. Obviously,then,if an accident occurs stopping thetimer before the hour intended, the working of the main combination isstillprevented, but at the same time there is a possibility of openingthe lockby the one person having the second combination, and so preventthe destruction or injury of the mechanism.

I have thus described mechanism in full by which my inventioninay becarried into practice; but I do'not wish to be understood as limitingmyself in all particulars to the especial devices here named andillustrated by the drawings,or their particular arrangement andadjustment here shown and set forth, for in many parts changes may bemade in many of the devices by substituting others which will performthe same work or by changing the arrangement and adjustment of thosewhich are here shown and described,while at the same time the main ideaof my invention is retained in full.

I have shown and described my improvement arranged to operate inconnection with only one of the tumblers, but obviouslyit may beconstructed and arranged to operate upon more than'one, if desired.

Having thus described my inventiomwhat I claim as new, and desire tosecure by Letters Patent, is
